Methods of Checking the Optical Characteristics of Soft Contact Lenses

  • Published:
Measurement Techniques Aims and scope

Abstract

A new classification is proposed for contact lenses based on standard specimens (tolerance monitoring). The best wavelengths have been determined for measuring the spectral transmission coefficients of the standard specimens, and realistic bounds have been defined for the tolerance fields for the most common colors of these lenses.
